Definitions
- the invention relates to a gas spring system for supporting wheel suspensions or axles on a vehicle body with a hose bellows arranged between a wheel-bearing or wheel-guiding connection and a vehicle body-side connection, which is mounted between a support element and a roll-off piston equipped with a pressure-resistant cavity, the support element and the roll-off piston are brought together via a central sliding joint.
- the problem on which the present invention is based is to develop a combined gas spring system which includes a displacer which is able to spring its gas volume in a simple manner. changes depending on the stroke.
- the system should function cost-effectively, with little maintenance and safely.
- a control tube is arranged on the support element supporting the hose bellows on the vehicle body.
- the latter is partially waisted on its outer wall, has beads or has openings in channels.
- the cavity of the rolling piston has a control sleeve which engages around the control tube with control clearance at least in some areas and, depending on the deflection stroke, completely or partially covers the waisted area which surrounds or openings.
- the control tube which plunges into the rolling piston when it is compressed, acts as a pneumatic valve spool, which connects or separates the gas volumes of the rolling bellows and the rolling piston cavity depending on the spring travel.
- Precise guidance of the rolling piston fixed on the axle or wheel suspension side by means of the piston rod articulated on the vehicle body of the shock absorber carrying the rolling piston enables the valve slide function of the steering tube in a simple manner.
- a pin which is guided in the bore of the head tube and is mounted on the axle or wheel suspension side and carries the rolling piston.
- the damper force can be adapted to the spring stiffness via the spring stroke.
- the groove length and length of the overflow channel in the damper then correspond to the waisted area or the beaded area of the head tube.
- Figure 1 Gas spring system with a hose bellows and inner guide in the middle position
- Figure 2 like Figure 1, but retracted position
- FIG. 3 like Figure 1, but extended position

- Figure 12 Head tube with internal channels.
- Figures 1 to 3 show a gas spring system usually installed in motor vehicles, which is installed, for example, per sprung wheel between the vehicle body and the axle or the corresponding independent wheel suspension.
- the pneumatic displacer (10) taking over the suspension is arranged around a hydraulic shock absorber (1).
- the shock absorber (1) has the function, inter alia, of a thrust joint, which ensures the precise relative movement of the suspension components when it is compressed and rebounded.
- the displacer (10) includes consisting of a support element (11), a rolling piston (50) and a hose bellows (15) connecting both parts.
- a rubber-elastic stop buffer (9) sits below the head plate (11) on the piston rod (4).
- the top plate (11) is essentially a round, flat disc on which the tubular roller bellows (15) is supported with its upper region.
- a control tube (20) for example, is screwed centrally onto the head plate (11) via a molded flange (21). On the outer edge of the on the Head plate (11) centered flange (21) abuts the upper bead (16) of the hose bellows (15).
- the control tube (20) which has the function of a Vent-Ligliedes within the gas spring system, has a central through hole (22) a f.
- the control tube (20) slides with the wall of this bore (22) on the outer jacket of the damper tube (2).
- the movement joint is sealed with a sealing element (27).
- the interior (29) of the head tube (20) has an ambient vent - not shown here - to the outside.
- the diameter of the bore (22) can be considerably larger than the diameter of the outer tube (2) of the damper (1).
- the volume of the interior (29) then adds to the cavity volume of the rolling piston (50).
- the outer wall (30) of the head tube (20) has four beads (32) or flats in the central region, cf. also FIGS. 4 and 5.
- a coherent, circumferential waist (31) can also be incorporated into the outer wall (30).
- spirally wound channels (34) with e.g. rectangular
- Single cross-sectional profile is provided, for example, the slope of adjacent channels have opposite slopes.
- Channels or beads (33) with a semicircular single cross section are shown in FIGS. 10 and 11.
- At least part of the edges of the waist (31), the beads (32, 33) and the channels (28, 34) and possibly the Bore edges (43, 44) can be rounded and / or polished to minimize flow resistance.
- the ratio between cross-sectional area and cross-sectional circumference should also be as large as possible.
- control tube (20) is constructed in the control area, for example by means of a sliding sleeve (40), with double walls.
- the sliding sleeve (40) is e.g. screwed onto the head tube (20) in a sealed manner with two sealing rings (45). It has, for example, a large number of radial bores (41), slots or other recesses in the upper and lower regions.
- the lower recesses (42) communicate with the upper recesses (41) via a circumferential annular groove (28) or individual channels that may be interconnected.
- annular grooves and / or channels can also be present in the inner wall of the sliding sleeve (40).
- the rolling piston (50) is a sleeve-shaped hollow body which is open at the bottom.
- the hollow body has i.a. to support the hose bellows (15) a e.g. cylindrical wall (51). It is welded with e.g. closed lid (52) arched down.
- the lid (52) has a central bore, which by means of a
- Mounting flange (53) is reinforced, cf. Figure 12.
- the mounting flange (53) rests on a plate flange (3) welded to the outer damper tube (2).
- the rolling piston (50) is held there with the aid of a spring ring (54).
- a seal is arranged between the plate flange (3) and the mounting flange (53), so that the rolling piston (50) is attached to the outer tube (2) of the damper (1) in a gas-tight manner.
- the upwardly oriented bottom (59) of the rolling pistons (50) has e.g. also a central opening, which is provided with a tubular control sleeve (60).
- the latter protrudes upwards above the floor (59) at least to the extent that it can form a radial contact for the lower bead (17) of the hose bellows (15).
- the bore (61) of the control sleeve (60) has an inner diameter that is slightly larger than the diameter of the outer wall (30) of the control tube (20).
- the control collar (60) forms a longitudinal slide valve together with the control tube (20).
- a sealing element (65) is e.g. an O-ring, a piston seal or the like.
- control sleeve (60) is located in the area of the beads (32) or the waist (31), the so-called comfort stroke area (6), cf. Figure 2.
- the cross sections of the waist (31), the total cross-section of the beads (32, 33) or the total cross-section of the channels (34) reduce the head tube cross section by a so-called overflow cross section.
- the latter are the non-hatched areas in FIGS. 5, 7, 9 and 11.
- the area of the overflow cross-section is between 5 to 20% of the maximum cross-sectional area of the bellows chamber (19) in the assembled state.
- control sleeve (60) The upper (63) and the lower control edge (64) of the control sleeve (60) are at a distance which is smaller than the distance between the most distant regions of the control edges (35, 36) on the head tube (20). These distances are measured in the stroke direction.
- the control sleeve (60) cannot completely cover the waist (31), the beads (32, 33) or the channels (34).
- the control collar (60) therefore has a negative switching overlap in FIGS. 1-11.
- the gas communicates in a spring stroke area (6) in which both control edges (63, 64) of the control sleeve (60) plus a minimum distance remain within the range between the upper (35) and lower control edge (36) of the control tube (20) of the bellows chamber (19) with the gas of the cavity (69).
- the spring stiffness is relatively low, so that comfortable driving is possible on a well-developed roadway.
- the measure for the minimum distance is calculated from the required cross-section.
- the communication described is also achieved in the comfort stroke area (6) as long as the upper control edge (63) moves below the bore control edges (43) and the lower (64) above the bore control edges (44).
- the overflow cross-sections are chosen to be so large that there is no noticeable throttling effect in the stroke area (6). In this way, unnecessary heating and a disruptive whistling noise can be avoided.
- additional fine control edges (37) can be incorporated at least on part of the control edges (35), cf. Figure 6.
- the amount of gas is first reduced in the bellows chamber (19).
- the variant from FIG. 12 also shows this load case.
- the control sleeve (60) covered the upper bores (1) or the bore control edges (43) for the usual sports stroke area (7). This prevents gas exchange with the rolling piston cavity (69).
- the control sleeve (60) with positive switching overlap works here.
- the high spring stiffness ensures safe wheel guidance on uneven road surfaces.
- FIG 3 there is the control collar. e (60) with its upper control edge (63) below the beads (32).
- the vehicle body has a particularly large ground clearance by inflating the cunning roller bellows (15).
- the gas volumes of the bellows chamber (19) and the rolling piston cavity (6 9) are - at least if the lower control edge (64) is below the Control edge (36) is located - separated from each other, making the spring stiffness relatively high. Possibly. this setting can be used for off-road driving.
- the bellows chamber (19) is connected to a corresponding gas storage device and / or a compressor system at least temporarily via gas-carrying lines that can be shut off.
- a valve control and position control completes the gas spring system for level control.
- the head tube (20) is described as a regular tube with a cylindrical outer contour and a cylindrical bore (22).
- the bore wall (62) is also shown as cylindrical.
- the control tube (20) can also be a regular or irregular polygonal profile in cross section, which also does not have to be completely closed in cross section.
- the control tube (20) can also be divided into several individual tubes or profiles arranged next to one another. In all cases, the open cross-section or sections of the control sleeve (60) are adapted to this or to these head tube cross-sections.
- Displacer support element head plate threaded bore bearing eye
- Hose bellows bead, top; below bellow chamber
